Firebase functions not listening for specific path

Question

I've a path in database /business/{businessId}/images/{imageId}/imageUrl It listens for business when a business in created, but later I'm pushing images in images, but it doesn't listen for businessImages. I used below listeners.

exports.business = functions.database.ref('/business/{businessId}').onWrite(event => {
    console.log('lorem epsum****', event);
    return true;
});

exports.businessImages = functions.database.ref('/business/{businessId}/images/{imageId}/imageUrl').onWrite(event => {
    console.log('lorem epsum****', event);
    return true;
});

What could be the issue?

Please update your question to include your database structure. — Jen Person, Oct 31 '17 at 13:40
If it possible that businessImages isn't firing because business is firing since it's watching a node higher up. Can you confirm whether or not exports.business fires when you write to any node below {businessId}? — DoesData, Oct 31 '17 at 13:45
I've mentioned already /business/{businessId}/images/{imageId}/imageUrl like `https://console.firebase.google.com/project/xxxxxxxx/database/data/business/-KxmM4e8pWKElDOcfD-b/images/-KxmM4gne1tl0yBbtJ_B/imageUrl` — Mohammad Kashif Sulaiman, Oct 31 '17 at 13:51
@DoesData Yeah, but it still doesn't work even if I remove `business` function. — Mohammad Kashif Sulaiman, Oct 31 '17 at 13:53
Include your database structure and the code where you write to the DB. — DoesData, Oct 31 '17 at 13:55
Isn't this database structure? `/business/-Kxm‌M4e8pWKElDOcfD-b/ima‌ges/-KxmM4gne1tl0yBb‌tJ_B/imageUrl` — Mohammad Kashif Sulaiman, Oct 31 '17 at 14:05
No. Go to your Firebase console and take a screenshot of the data so we can see where you are writing / listening for data changes. We can't verify that your path is correct without seeing the structure. You can take a look at a question I asked that includes images of the structure here: https://stackoverflow.com/questions/46008814/efficiently-determine-if-user-liked-post-in-firebase — DoesData, Oct 31 '17 at 16:22
@MohammadKashifSulaiman if you want to trigger when an image is added apply trigger on `/business/{businessId}/images/{imageId}` — Inzamam Malik, Nov 02 '17 at 13:20
instead of `/business/{businessId}/images/{imageId}/imageUrl` — Inzamam Malik, Nov 02 '17 at 13:20

Thank you every one for the answers, but the main issue was, i was inserting the whole base 64 images in the imageUrl, resulting in slowest performance for listening or getting data for imageUrl. When i removed all the images, it worked great.

P.S. I know we should put URLs instead of base 64 images.
